Looking for a sensors for food computer which can survive big humidity

Hello everyone!
First of all, sorry if that not the best forum to ask questions like that, but the forum seems pretty vivid so I decide to try
I'm building a food computer and I'm looking for a stable way to sense humidity in food computers.
Previously, I've been trying DHT22, Si7021, but they are pretty glitchy with RH > 90%, and sometimes not working at all. After putting them back to the normal condition they seem to work, but provide totally incorrect data.
HS1101 sensor does a better job and can survive with big humidity but during RH>90% it's giving incorrect metrics data after a few weeks of working. Each day his errors growing for about ~0.05% => in 30 days we have 1.5% infelicity which is crucial. Having so big humidity error can burn or overflood crop in the container.
So does anyone know any good humidity sensors?
Thanks, everyone
